Process gas analyzer: density, pressure, temperature
Sarasota SG901 Thermo Scientific - Process Systems

The reliable Thermo Scientific Sarasota SG901 (formerly SG900) specific gravity analyzer is a self-contained bypass sample conditioner that measures density, pressure and temperature of dry and wet gases. This more compact model features fast response and continuous, high accuracy measurements to 0.2% of reading, making it an ideal choice for a variety of applications.

The rapid response of the SG901 ensures effective burner, furnace and flare gas monitoring and control. It is recommended in applications where specific gravity (SG) or molecular weight (MW) can be used to infer density elsewhere in the plant and where the gas is dirty or wet and requires filtering prior to the measurement.

The SG901 is available in three configurations: a basic system, a dry gas system and a wet gas system. It comprises a Thermo Scientific FD900 gas density assembly, temperature element and flow control valve. Built to endure harsh environments, the SG901 requires minimal maintenance and no on-site calibration is necessary.
